nginx 0.3.54 *) Feature: nginx now logs the subrequest information to the error log. *) Feature: the "proxy_next_upstream", "fastcgi_next_upstream", and "memcached_next_upstream" directives support the "off" parameter. *) Feature: the "debug_connection" directive supports the CIDR address form. *) Bugfix: if a response of proxied server or FastCGI server was converted from UTF-8 or back, then it may be transferred incomplete. *) Bugfix: the $upstream_response_time variable had the time of the first request to a backend only. *) Bugfix: nginx could not be built on amd64 platform; bug appeared in 0.3.53.
